Reaktionsschritte
The procedure is as in Example 2 for the preparation of diethyl 2-dimethylamino-5-phenylthio-2,4-hexadienedioate, starting with N-(3-dimethylamino-3-ethoxycarbonylpropenylidene)-N-methylmethanaminium tetrafluoroborate (15.7 g), a 2M ethanolic solution of sodium ethylate (27.5 cc) and ethyl (benzylthio)acetate (11.6 g) in ethanol (110 cc). Diethyl 5-benzylthio-2-dimethylamino-2,4-hexadienedioate (19.2 g) is thereby obtained, and is used in the crude state in the subsequent phases.
